Abstract
(EN)
The objective of the present invention is to improve reliability by ensuring a high degree of safety, while heating each battery cell. This power source device is provided with a battery block (10) comprising a plurality of battery cells provided at either end with a positive electrode and a negative electrode, lead plates (2) connected to the positive electrode and the negative electrode of each battery cell, to electrically connect the battery cells, and sheet heaters (3) for heating the battery cells, wherein the sheet heaters (3) are laminated in a thermally bonded state onto one surface of each battery cell, on the negative electrode side thereof, with the lead plate (2) interposed therebetween.

La présente invention a pour objectif d'améliorer la fiabilité en garantissant un degré élevé de sécurité, tout en chauffant chaque cellule de batterie. Le dispositif source d'alimentation selon l'invention est pourvu d'un bloc de batterie (10) comprenant une pluralité de cellules de batterie pourvues à chaque extrémité d'une électrode positive et d'une électrode négative, des plaques de plomb (2) connectées à l'électrode positive et à l'électrode négative de chaque cellule de batterie, pour relier électriquement les cellules de batterie, et des éléments chauffants en feuille (3) destinés à chauffer les cellules de batterie. Les éléments chauffants en feuille (3) sont stratifiés dans un état lié thermiquement sur une surface de chaque cellule de batterie, sur le côté de son électrode négative, avec la plaque de plomb (2) interposée entre ceux-ci.
